Air pollution models that can be used to predict pollution concentrations for periods of up to a year are generally semi-empirical/analytic approaches based on Gaussian plumes or puffs. These models typically use either a simple surface-based meteorological file or a diagnostic wind-field model based on available observations. The Air Pollution Model (TAPM) (Hurley 1999), newly developed in CSI...

Dispersion of releases in urban areas can be estimated with information on micrometeorological variables in the urban boundary layer. However, this information is not generally available. On the other hand, meteorological measurements are routinely made in rural surroundings (e.g. airports). We examine empirical relationships between urban and rural meteorological variables using data from the ...

So far we have seen two of the main inputs of an application performance model: its Performance-DNA and the usage volume. In my appreciation of modeling it is of crucial importance to be able to analyze the performance of both the application as whole and each of its transaction types individually. This is called Transaction Aware Performance Modeling or TAPM. So Performance-DNA preferably shou...

Porphyrin‐based porous organic polymers (Por‐POPs) are attracting increasing attention because of their potential in visible light photocatalysis. The distinctive attributes Por‐POPs have been elucidated by investigating response to specific reactions, such as the aerobic oxidation sulfides. However, most researchers choose porphyrin molecules with relatively short peripheral substituent chains...

Air pollution primarily originates from substances that are directly emitted natural or anthropogenic processes, such as carbon monoxide (CO) gas in vehicle exhaust sulfur dioxide (SO2) released factories. However, a major air problem is particulate matter (PM), which an adverse effect of wildfires and open burning. Application tools for monitoring risk areas using real-time with drones have em...

BACKGROUND The waste transfer stations (WTSs) is one of the most important factors affecting on environment and human health. This research is aimed to evaluate health risk of VOCs among WTS personnel and provide a model for dispersion of VOCs. The Air Pollution Model (TAPM) is able to simulate WTS emissions dispersion over each town. RESULT GC-MS was used to analysis collected gas samples to...

Particulate matter represents a serious hazard to human health, and air quality models contribute the understanding of its dispersion. This study describes particulate with ≤10 μm diameter (PM10) dynamics in an urban–industrial area, through comparison three datasets: modeled (TAPM—The Air Pollution Model), measured concentration (environmental control stations—ECS), leaf deposition values.
